Decrease in crew performance is frequently cited as a major causal factor in maritime accidents. Although considerable researches on working hours undertaken by seafarers have been conducted through interviews and record analyses, experimental studies on the effects of factors, such as high workload, shift patterns, stress, sleep deprivation, and disturbance on the cognitive performance of mariners have been limited. Other safety-critical transport industries, such as aviation and rail, have developed fatigue management tools to help managements in the work patterns of their operators. Such tools for mariners would assist shipboard crews, marine pilots, and shore managers for planning and improving work schedules. The overall aim of this paper is to determine a fatigue factor that can be applied to human performance data as a part of a software program that calculates total cognitive performance. This program enables us to establish the levels of cognitive performance in a group of marine pilots in order to test a decision-making task based on radar information. This paper addresses one of the factors that may contribute to the determination of various fatigue factors: the effects of different work patterns on the cognitive performance of a marine pilot.

Objectives: This study identified factors impacting radiation knowledge among aircrew, who are affected by cosmic radiation exposure due to their occupational environment. Methods: In September 2019 we conducted an online survey of aircrew through a Google link. We evaluated the level of radiation knowledge using a ten-item (10 points) questionnaire. The following exploratory variables were evaluated in relationship with the level of radiation knowledge using univariable linear regression models: sex, age, duration of employment, position level, company, marriage, education level, personal/family history of disease, and the number of times acquiring information on radiation through various channels (internet searching, watching television, reading newspaper, conversation about radiation with aircrew/non-aircrew, in-house training). With a p of 0.2 in univariable models, we built a multivariable linear regression model using a stepwise selection method. Results: The average radiation knowledge score of the 356 respondents was 7.22. Univariable linear regression analysis showed that radiation knowledge of the aircrew was associated with their company, position level, age, and number of conversations with other aircrew members. Our multivariable model showed that the radiation knowledge level of aircrew decreased as they had more conversations about radiation with other aircrew members and as their age increased. Conclusions: Korean air crew showed a lower level of radiation knowledge as their age and the number of conversations with colleagues increased. The study suggests that more education is needed in order for aircrew to gain accurate radiation knowledge.

Purpose: As communicable disease, COVID-19, pandemic strikes over the world, it is critically bewared that air travel possibly be a major pass way to deliver the infectious disease virus. Especially the airplane could be an unique environment to cultivate the virus spreaders. In order to keep the continuous safe airway as well as the industry, related international associations and organizations have been published the guidelines for the prevention and control the infectious disease through the all aspects of aviation. By reviewing the guidelines, focusing on the in-flight infection prevention and control, this study would not only inform a summary of the international guidelines but also provide an essential and general consideration for related research or guideline study. Methods: Guidelines of 5 major countries are reviewed, which has been seriously influenced by COVID-19 : U.S., Canada, E.U., Australia and China. The items of the guidelines are re-categorized as its similarity and structure by applicable cases. Results: The result of this study shows that each guideline seems to share a major structure and issue such as identifying sick traveler, sick passenger care, and cleaning even though that of China has a different since it used to consider the flight conditions based on 3 levels of infection risk. For sick passenger care, the guidelines includes crew safety, service level, sick passenger isolation, and cleaning. Implications: A published guideline as a public manual could be to prevent and control the in-flight infection efficiently and promptly. It also could provide a confidence of knowledge and educate for all users to prepare the in-flight emergency as well.

Purpose: The purpose of this study is to analyze the effect of self-leadership on self-efficacy and customer orientation and to verify whether there is a mediating effect of self-efficy on the relationship between self-leadership and customer orientation. Methods: To verify these research problems, the subjects of this study were a total of 300 Korean cabin crew members working for domestic and foreign airlines who received distributed questionnaires and 247 copies wee analysed using the SPSS 20.0 program. Results: First, it can be seen that the self-leadership of airline cabin crew has a significant positive (+) effect on self-efficacy, indicating that self-leadership has a positive effect on the self-efficacy of the members of the organization. Second, it was found that self-efficacy had a positive (+) effect on the customer orientation of airline cabin crew, and it was analyzed that self-efficacy played a partial mediating role in the relationship between self-leadership and customer orientation. Third, it was found that self-leadership had a positive (+) effect on customer orientation, and it was proved that behavior-oriented strategy, constructive accident pattern, and natural compensation strategy, which are three sub-factors of self-leadership of cabin crew, have an influence on customer orientation. Conclusion: based on these findings, the theoretical and practical implications of this study and directions for future research were presented.

Work and family are two major fields of one's life. In the past, the role of each gender has been separated, and there was no conflict between two fields. However, the increasing rate of working woman and the mode of social change that the male has also responsible of caring family and individuals has more interested in their personal life make consider these two fields as a whole. A number of studies have shown that OCB contribute in important ways to organizational functioning and performance. Whereas citizenship behavior may affect organizations in several positive ways, it is also possible that engaging in such behaviors could have negative consequences for the employees who do so. There may be other personal costs such as work-family conflict that accrue to individuals who engage in high levels of citizenship behavior. The purpose of this study is to investigate the moderating effect of the SOC strategy and Family Friendly Atmosphere on the negative effects of OCB on Work-Family Conflict. Questionnaire data were collected from 590 in different jobs. According to the result of empirical analysis, it proved that the more OCB effect on the more Work-Family Conflict. it also was found that the SOC strategy and Family Friendly Atmosphere moderate the relation between OCB and Work-Family Conflict. At the end of the paper, theoretical and managerial implications of this study, future research directions are discussed.

The most decisive factor of major sources of a helicopter is the main rotor system and the rotor-induced vibration is one of the technical challenges which should be resolved to ensure comfort for crews and passengers. Passive vibration reduction devices are adopted in conventional helicopters and several types of passive devices are also used in Surion. In recent years, foreign helicopter manufactures have increasingly applied the application of AVCS (active vibration control system) because of their superior performance with lower weight compared to passive device. In addition to weight reduction, AVCS has advantages maintaining its performance over aircraft configuration changes and flight condition changes. The technology demonstration program was performed in order to validate the performance of AVCS when applied to Surion, and optimization process for finding optimal configuration of sensors and actuators. Optimal configuration was produced using ground and flight test data, and its performance was evaluated and compared with flight test result.

The purpose of this study is to suggest a customized servant leadership by exploring the effects of stewardship and community building factors on the subordinates' trust in leader of lower hierarchy and their job engagement. Regression analysis showed that stewardship is higher than community building in terms of its influence on job engagement, while community building outstrips stewardship in terms of trust in leader. Specifically, two items of stewardship factor - valuing the opinions of the subordinates in decision-making, and sacrificing without giving priority to the leader's self-interest - influenced the subordinates' trust in their leader. Of the items in community building, cooperating rather than competition, abiding by the principles in performing the work, the leader's not seeking recognition or compensation, and giving the subordinates the necessary authority to perform their work put impacts on the subordinates' trust in the leader, as well. As for job engagement, helping subordinates grow and develop, and, if necessary, taking the risk of challenging the job have a significant impact. Among the items of community building, it was found that the leader's not seeking recognition or compensation, and keeping the principles strictly in performing her duties promote job engagement. Based on these results, we propose to managers of human resources department the selection and training of tailored talents to meet the environmental characteristics of each organization, while avoiding programs for hiring and training personnel equipped with the uniform qualities of servant leadership.
